工資、工作配合與工作轉換之期間分析的實証研究

林建志, Lin, Steve Unknown Date (has links)
本論文將勞動市場的狀態過程說明非常完整,即是勞動者的搜尋過程、工作配合過程都是詳細介紹其理論背景,以及實証的結果。由於,在勞動市場上,由於勞動者與廠商之間的訊息不完全,造成勞動者與廠商兩者之間往往無法一拍即合,而導致勞動者可能離職他就,廠商亦可能另聘高明,於是工資變動與工作異動就成為經常看到的現象。 在本文研究勞動者工作異動的情形,在理論模型上是以工作契合理論為基礎,而要討論工作契合理論的基礎則必須先知道Lippmam與MaCall(1976)所提出的工作搜尋理論。因為工作契合理論又是以工作搜尋理論為基礎,因此在理論模型上必先討論工作搜尋理論,進而討論工作契合理論。 文中研究主要藉由民國八十五年九月高希均教授與林祖嘉教授於八十四年四月至八十五年六月期間針對民國八十一年六月專上畢業生的資料,分析全体專上畢業生、女性專畢業生與男性畢業生在工資、工作契合期間與勞工離職率決定以及動態行為決定。並且我們把這些資料分為四大類基本資料:個人背景資料、工作配合資料、人力資本資料與工作特徵及其基本資料。在工資的模型方面則利用一般的最小平方法來估計,因為假設市場上的工資分配為一常態分配,是一般實証文獻常用的。就勞工的契合期間,我們運用林祖嘉(1991)的模型,本文則用在勞動者的離職率與工作契合期間的決定。我們分為四個模型,分別是:Weibull、exponential、lognormal與logistic四種分配。在勞工離職方面我們運用了Cox(1972)的比例危險率模型,Lynch(1991)首次將之運用在勞動者工作異動的決定,除此之外,我們也進一步的討論工資、工作契合期間與離職率的進一步的動態的分析。

以漢語趨向動詞「起來」、「下去」、「上來」為例的語法化研究 / On Mandarin Directional Verbs Qi-lai, Xia-Qu, and Shang-lai: A Reflection of Grammaticalization

李陳福, Li, Chen-Fu Alfred Unknown Date (has links)
本篇論文引用Hopper在1993年所提出的五項原則,論證漢語中「起來」、「下去」、「上來」的多義現象是反映語法化的現象。在「起來」、「下去」、「上來」語法化的過程中,可以發現許多語意和語法的痕跡,例如語意選擇的限制、受詞位置的限制、受詞限定的要求、與完成貌時貌標記使用的限制。根據Lehmann 1991年的研究,這些痕跡說明「起來」、「下去」、「上來」在語法化的過程中是由「子句中」向「子句間」變動。這樣的語意變動主要來自於概念上由空間向時間的比喻轉換。除此之外,在「起來」、「下去」、「上來」的句子中,這樣的轉換還受到不同的語意角色要求所限制。 / This thesis applies Hopper*s Principles (1993) to assert that the semantic varieties of Mandarin directional verbs qi-lai, xia-qu, and shang-lai are reflections of grammaticalization. The grammaticalization of Mandarin qi-lai, xia-qu, and shang-lai has left traces on selectional restriction, syntactic constraints on object positions, object definiteness, and requirements of perfective aspect marker. Based on Lehmann (1991), these traces lead to the conclusion that Mandarin qi-lai, xia-qu, and shang-lai shift from clause-internal to cross-clause grammaticalization. The semantic shifts of Mandarin qi-lai, xia-qu, and shang-lai are considered to be motivated by SPACE-to-TIME metaphorical transfer. The transfer is also constrained by theta-role requirements.

台灣省各地區普查資料之統計分析

莊靖芬 Unknown Date (has links)
本研究的目的為研究台灣省在1990年之15-17歲的在學率,在找出可能影響因素並蒐集好相關的資料後,我們將蒐集到的資料分成兩個部份,一個部份用來建造模型,而另一個部份則用來測試所建立出來的模型。主要的過程是:先利用簡單迴歸模型了解各個可能的因素對於15-17歲的在學率的影響程度,經過許多分析及了解後再對這些變數採取可能的變數轉換(variable transformations),而後再利用三種常用的統計迴歸方法﹝包含有逐步迴歸(stepwise regression)方法、前進選擇(forward selection)方法以及後退消除(backward elimination)方法﹞去發展出一個適當的複迴歸模型(multiple regression model)。對於這個模型,以實際的台灣在學情況來看,我們看不出它有任何的不合理;同時也利用圖形及檢定去驗證模型的假設,其次還做有關迴歸參數的推論(inferences about regression parameters)。再其次,我們運用變異數分析的結果(analysis of variance results)以及新觀察值的預測情形(predictions of new observations)來評估模型的預測能力。最後並利用所得到的最適當的模型,對如何提昇15-17歲青少年的在學率給予適當的建議。 / The objective of this research is to study what factors may affect the schooling rates of 15-17 years old in Taiwan province in 1990. After finding out some possible factors and collecting those data regarding those factors, we separate the data (by stratified random sampling) into two sets. One set is used to construct the model, and the other set shall be used to test the model. The main process to build a regression model is as follows. First, we shall use simple linear regression models to help us to see if each factor may have relation with the schooling rates. With the analysis of residuals and so on, we then make appropriate transformations on each of these factors. Finally, we use three common statistical regression techniques (including stepwise regression, forward selection, and backward elimination methods) to develop a suitable multiple regression model. It seems that, by our understanding of schooling rates in Taiwan, this model is not unreasonable. In addition, we verify the assumptions of the model by graphical methods and statistical tests. We also do the inferences about regression parameters. Furthermore, ye use the results of the analysis of variance and predictions of new observations to evaluate the prediction ability of the model. Finally, we use the most appropriate multiple regression model to give some suggestions to improve (or keep) the schooling rates of 15-17 years old.

轉換型領導對警政服務品質之影響研究 / The Influence of Transformational Leadership on the Quality of Police Service

陳譓森, Chen, Hui Sen Unknown Date (has links)
警政部門雖是公共行政的一環,但是由於在傳統上,其任務多注重在社會治安的維護與公共秩序的維持,警察的角色被塑造或自我塑造成「犯罪的打擊者」、「法律的執行者」、「正義的捍衛者」。然而基於社會的變遷腳步,傳統的警察角色已逐漸無法適應不斷變遷的民眾需求,民眾要求的不但是警察的力量應足以保障生命與財產安全而已,更要求警政部門所採行的策略能解決他們最為切身的問題。   然而欲使警察的各項作為從「破大案,捉要犯」轉變為以探求民眾切身的問題為主的策略,等於是要警察從注重績效數字的文化轉變為注重品質的文化,在本質上,這是一種 「外部變革」(external change),以滿足民眾的需求為目標,此與近年來歐、美各國公共部門所推動的「全面品質管理」(total quality management)以及警政部門所實施的「社區警政」(community policing)的理念與目標均甚為一致。學者們研究指出,欲達成此-「外部變革」的目標,必須要先完成組織的「內部變革」(internal change),對警政領導階層而言 ,他們必須實施「品質領導」(quality leadership),才能澈底改變員警對於警政服務工作的態度與滿意度。易言之,警政領導階層必須具備品質遠景、堅強的信念、以及採取行動的決心,積極扮演品質策略的發動者角色,才能引領所有員警澈底轉型,從自利的追求,轉而關注於公共利益的追求,此一理念就是Bernard M. Bass所倡導的「轉換型領導」(trandsformational leadership)與「交易型領導」(transactional leadership)的綜合運用。   因此,本研究首先將「交易型領導」視之為達成警政服務品質遠景的管理策略,而將「轉換型領導」視之為促使警察人員在態度上全盤轉變的文化轉型策略,深入探討這兩個理論的內涵以及二者的整合效果;第二,從思想演進、學術背景等兩方面探討警政服務品質的理論基礎,並依「全面品質管理」與「社區警政」的相關理念,指出「公正性」、「認真執勤」、「服務社區」等三個警政服務品質的決定性面向;第三,將「轉換型領導」與「警政服務品質」這兩個理論領域加以結合,提出提昇警政服務品質的轉換型領導策略;第四,以我國縣市警察局相關人員為研究對象進行實證研究,除了嚴格要求信度、效度、以及樣本代表性之外,並深入分析轉換型與交易型領導因素對警政服務品質的影響關係,從而驗證本文的研究架構;最後根據實證分析與說明提出研究發現,並從理論研究、實務運用、後續研究等三方面分別提出研究建議。

高解析離散逆轉換方法之應用 / Applications on High-Resolution Inversion of the Discrete Transformation

林志哲, Lin, Chih Che Unknown Date (has links)
高解析法是訊號處理上處理離散訊號系統的重要方法,將之運用在有限二項組合及有限卜瓦松組合的參數解上,可以得到很好的結果。本篇論文除了將高解析法在有限二項組合及有限卜瓦松之運用作一探討外,並在有限二項組合的基礎上推論有限負二項組合在特殊情況下的解法。 / High-resolution inversion method is an important technique to solve discrete signal system problems. We can solve finite binomial mixtures and finite Poisson mixture problems with high-resolution inversion method. In thispaper, we shall provide and discuss how the high-resolution inversion method used in finite binomial mixtures and finite Poisson mixture problems.In addition,we shall also extend our methods to solve finite negative binomial mixture problems with some assumptions same as those for finitebinomial mixtures.

關於週期性波包近似值的理論與應用 / On the Theory and Applications of Periodic Wavelet Approximation

鄧起文, Deng, Qi Wen Unknown Date (has links)
在本篇論文裏,我們將使用所謂的週期化(periodization)的裝置作用於Daubechies' compactly supported wavelets上而得到一族構成L<sup>2</sup>([0,1])和H<sup>s</sup>-periodic (the space of periodic function locally in H<sup>s</sup>)基底的正交的週期性波包(orthonormal periodic wavelets)。然後我們給出了對於一函數的波包近似值的誤差估計(參閱定理6)以及對於週期性邊界值的常微分方程問題的解的波包近似值的誤差估計(參閱定理7)。對於Burger equation的數值解也當作一個應用來討論。 / In this thesis,we shall construct a family of orthonormal periodic wavelets which form a basis of L<sup>2</sup>([0,l]) and H<sup>s</sup>-periodic (the space of periodic functions locally in H<sup>s</sup>) by using a device called periodization ([10,7]) on Daubechies' compactly supported wavelets.We then give the error estimates for the wavelet approximation to a given function (see theorem 6) and to a solution of periodic boundary value problem for ordinary differential equation(see theorem 7). Numerical solution for Burger equation is also discussed as an application.

俄國女性革命家 維拉‧沙蘇里契及其政治思想轉換

劉淑芬 Unknown Date (has links)
本文題目為「俄國女性革命家 維拉‧沙蘇里契及其政治思想轉換」,專述沙蘇里契的生平要事與其思想轉換過程。好比她在勞動解放社和俄國社會民主黨在十九世紀末的紛爭,另外在火星報時期列寧和普列漢諾夫之間的紛爭中也可以看出沙蘇里契的樞紐角色。在幾乎二十五年的時間裡,在反政府恐怖主義運動中,她不得已地刺殺了德列波夫之後,她便拋棄了恐怖暴力革命之思想,並在土地與自由社的分裂當中,吸引一些追隨者隨她加入黑土重分社,同樣地她在一八八三年更有助於發掘第一個俄國馬克思主義社會,如此一來,永久地分裂了民粹主義,長久以來換得了一個激進的社會主義觀點。一度在一九○三年,沙蘇里契扮演一個在孟什維克派與布爾什維克派的分裂中重要的角色。   不難發現其所每次之轉變,她好爭論的工作之進程也在這些分裂之中,近三十多年的著作,她的影響確實在社會主義的世界裡,令人深切的感受到。   本文目的主要在於分析三個問題:   一、俄國女性革命家─維拉‧沙蘇里契其先後思想更迭之因素;   二、俄國女性革命家─維拉‧沙蘇里契和列寧之關係轉換與俄國政治型態更替之關係;   三、俄國女性革命家─維拉‧沙蘇里契晚期思想分析。   綜上所述,第一章將以序論為楔子,敘述研究動機、文獻探討、研究目的、研究限制、研究架構。第二章則題為沙蘇里契革命思想之形成,也就是與涅查耶夫相識的形成期。   第三章則題為從民粹主義至馬克思主義的思想轉換,也就是銜接沙蘇里契的自我形成與之參與民粹派活動。第四章則題為馬克思主義中的維拉‧沙蘇里契,此段時期為她一生中革命事業與地位之最高峰。第五章題為一九○九年至一九一四年的取消派與維拉‧沙蘇里契。第六章題為十月革命以後的維拉‧沙蘇里契,此時已然為沙蘇里契在政治舞台上最後一段時期。第七章為結論部分,主要呈現研究目的與研究結果相互回應下所產生的維拉‧沙蘇里契之思想原貌與轉變原因,並利用垂直分析,來使讀者清晰本論文之目的與結論,更進一步回應本文之研究目的。 / The topic of this dissertation is “ The Russian female revolutionist- the life of Vera Zasulich and her transformation of political conviction.” The focus of this research is her life and the transformation process of her political conviction. For example, her role in the Liberation of Labour, Social Democratic Labour Party, and her relationship with Plekhanov and Lenin.   At first, the focus is an introductory part in a piece of this research. In the second chapter, touching upon her life, she was born into a poor family in 1849. Her father died when she was three years old and as her mother was unable to cope, she sent Vera to live with wealthy relatives in Biakolovo. When Zasulich finished her schooling she moved to St. Petersburg and found work as a clerk. She became involved in radical politics and met Sergi Nechayev, the co-author with Mikhail Bakunin of Catechism of a Revolutionist. Zasulich joined a weaving collective and became active in the movement to educate workers, conducting literacy classes for them in the evenings.   In the third chapter, the focus is her transformation from a populist to a Marxist. In 1876, Zasulich found work as a typesetter for an illegal printing press. A member of the Land and Liberty group, when Zasulich heard that one of her fellow comrades, Alexei Bogoliubov, had been badly beaten in prison, she decided to seek revenge. Zasulich went to the local prison and shot Dmitry Trepov, the Governor General of St. Petersburg. She was arrested and charged with attempted murder. During the trial the defence produced evidence of such abuses by the police, and she conducted herself with such dignity, that the jury acquitted her. When the police tried to re-arrest her outside the court, the crowd intervened and allowed her to escape.   In the fourth chapter, the focus is the role she played in the Marxist period. In 1883, Zasulich joined with George Plekhanov and Paul Axelrod to form the Liberation of Labour, the first Russian Marxist group. Later she moved to Switzerland where she became active in the Social Democratic Labour Party (SDLP) and served on the editorial board of Iskra.   From the fifth to the seventh chapter, the key point is the latter part of her life. At the Second Congress of the Social Democratic Labour Party in London in 1903, there was a dispute between Vladimir Lenin and Jules Martov, two of SDLP''s leaders. The last part, she returned to Russia during the 1905 Revolution but after its failure ceased to be active in politics. During the First World War Zasulich supported the war effort and opposed the Bolshevik Revolution. Vera Zasulich died in 1919.   The objective of this research is to analyze three subjects:   1.The causes of her transformation in her political conviction.   2.The relationship between Zasulich and Lenin under changing of the Russian political form.   3.The thinking of the latter part of Zasulich''s life.

希爾柏特黃轉換於非穩定時間序列之分析:用電量與黃金價格 / Non-stationary time series analysis by using Hilbert-Huang transform: electricity consumption and gold price volatility

張雁茹, Chang, Yen Rue Unknown Date (has links)
本文有兩個研究目標,第一個是比較政大用電量與氣溫之間的相關性,第二則是分析影響黃金價格波動的因素。本文使用到的研究方法有希爾柏特黃轉換(HHT)與一些統計值。   本研究使用的分析數據如下:政大逐時用電量、台北逐時氣溫以及倫敦金屬交易所(London Metal Exchange)的月平均黃金價格。透過經驗模態分解法(EMD),我們可以將分析數據拆解成數個互相獨立的分量,再藉由統計值選出較重要的分量並分析其意義。逐時用電量的重要分量為日分量、週分量與趨勢;逐時氣溫的重要分量為日分量與趨勢;月平均黃金價格的重要分量則是低頻分量與趨勢。 藉由這些重要分量,我們可以更加了解原始數據震盪的特性,並且選出合理的平均週期將所有的分量分組,做更進一步的分析。逐時用電量與逐時氣溫分成高頻、中頻、低頻與趨勢四組,其中低頻與趨勢相加的組合具有最高的相關性。月平均黃金價格則是分為高頻、低頻與趨勢三組,其中高頻表現出供需以及突發事件等短週期因素,低頻與歷史上對經濟有重大影響的事件相對應,趨勢則是反應出通貨膨脹的現象。 / There are two main separated researched purposes in this thesis. First one is comparing the correlation between electricity consumption and temperature in NCCU. Another one is analyzing the properties of gold price volatility. The methods used in the study are Hilbert-Huang transform (HHT) and some statistical measures.   The following original data: hourly electricity consumption in NCCU, hourly temperature in Taipei, and the LME monthly gold prices are decomposed into several components by empirical mode decomposition (EMD). We can ascertain the significant components and analyze their meanings or properties by statistical measures. The significant components of each data are shown as follows: daily component, weekly component and residue for hourly electricity consumption; daily component and residue for hourly temperature; low frequency components and residue for the LME monthly gold prices.   We can understand more properties about these data according to the significant components, and dividing the components into several terms based on reasonable mean period. The components of hourly electricity consumption and hourly temperature are divided into high, mid, low frequency terms and trends, and the composition of low frequency terms and trends have the highest correlation between them. The components of LME monthly gold prices are divided into high, low frequency term and trend. High frequency term reveals the supply-demand and abrupt events. The low frequency term represents the significant events affecting economy seriously, and trend shows the inflation in the long run.

台灣上市上櫃公司發行可轉換債券之存活分析研究 / Survival analysis for convertible bonds of listed companies in Taiwan

戴誠蔚 Unknown Date (has links)
可轉換公司債為複合式證券,除了具有債券性質外,並給予持有者於債券流通期間內行使轉換為股票之權利。以存活分析方法探討可轉債之研究尚屬少見,本論文乃以台灣上市櫃公司發行之5年期可轉債為研究資料,先整理出與公司經營有關的變數,再分別以Cox模式與再發事件之兩種邊際模型(marginal model):A-G (Anderson-Gill) 模式、PWP-TT (Prentice-Williams-Petersen)模式為研究分析方法,探討可轉債之流通時間及大量交易時間的問題。本論文並將可轉債分類為債券類型、混合類型和權益類型,且由於不同類型可轉債之流通時間有所差異,因此以其為分層條件加入模式中進行分析。研究結果發現,資產總額、總負債率、TCRI評等及董監持股率等變數,具有顯著解釋可轉債流通時間的能力,可見公司財務負債狀況與穩定性與流通期間有關;而最高差價(當月最高股價與轉換價之相對差價)、長期負債率、總負債率及股價報酬率等變數,則可顯著解釋大量交易的發生時間,表示公司財務負債狀況與股價利潤差與大量交易發生之快慢有關,其中資產總額、最高差價、TCRI評等及股價報酬率之係數均顯著為正,長期負債率、總負債率及董監持股率之係數則顯著為負。由於平均表現之存活曲線與經驗存活曲線相當接近,以Kolmogorov-Smirnov檢定多無顯著差異,顯示這些模式有不錯的配適能力;至於對個別公司估計出之存活曲線,則或有與經驗存活曲線相差較多的現象,顯示所建立的模式可對個別公司提供可轉債即將結束流通或發生大量交易之預警。 / Convertible bonds are hybrid securities that possess the properties of bonds and the right to convert bonds into shocks. Few articles employed survival analysis to analyze the characteristics of convertible bonds. To investigate the effects of the issuer’s financial information to the duration of circulation and the timing of the massive trading about convertible bonds, Taiwan’s 5-year convertible bonds were collected, and three methods of survival analysis were employed:Cox model、A-G (Anderson-Gill) model and PWP-TT(Prentice-Williams-Petersen) model. We classified convertible bonds as debt-like, equity-like, and hedge-like, and then make the classification as a stratification condition later. In summary, total Assets, total debt ratio, TCRI, and the proportion of holding share in supervisors and directors are significant variables on circulation period of convertible bonds. Apparently, the extent of debt and financial stability of issuers have significant effects on circulation period; the difference between stock price and conversion price, long-term debt ratio, total debt ratio and stock return rate contribute significantly on the timing of massive trading of convertible bonds. While the extent of debt and the return of stock hasten the hazard of the timing of massive trading. Furthermore, there are no significant differences between the survival curves evaluated at the average performance levels and the corresponding empirical survival curves, according to the results of Kolmogorov-Smirnov test. However, the differences between individual survival probabilities and overall empirical survival probabilities might be large, which indicates that the models incorporate companies’ performance overtime may provide a warning message for the termination of circulation or the timing of massive trading for a particular convertible bond.

模 糊 無 母 數 統 計 檢 定 及 其在 高 齡 化 社 會 調 查 之 應 用 / The Fuzzy nonparametric statistical test and its application on the survey of an aging society

趙淑倫 Unknown Date (has links)
在逐漸高齡化的社會中,關注老人的生活議題並加以分析益顯重要。在研究老人問題時,由於研究對象均曾經歷不同的時空背景與人生閱歷,各個體間存在的差異極大;不同族群的老人對其所慣用語彙的理解與表達亦不盡相同。故若利用傳統的統計分析研究結果,強迫人們採用二元邏輯的方式思考與解釋,可能會導致偏差或錯誤的結論。且傳統的統計檢定方法,往往假定取樣的樣本滿足某個分配,因而導致過多的解釋,影響決策品質。 因此,為避免因誤解老人而造成虛耗社會成本,使有限的社會資源得以充分運用,本文於研究老人身心特質與個人期待時,嘗試以模糊理論的軟計算,提出反模糊化轉換。並應用中位數檢定及變異數檢定,建立當統計參數為模糊數或模糊區間時之小樣本無母數模糊統計檢定方法模型。由實證例子分析結果顯示,我們提出的檢定方法,能有效分析模糊樣本的問題,並進而期望能對老人議題的分析和決策有所貢獻,及將此方法運用於其它模糊性議題之研究。 / In a gradually aging society, it is important to pay attention to and then analyze elderly people’s life issues. When a study about elderly people is undertaken, the subjects are very inconsistent given their diverse life experience, and various subgroups of subjects have quite different understanding of and way of expressing a vocabulary. Therefore, analyzing study result with conventional statistical analysis method, which forces thinking in a binary logic way, may lead to biased or erroneous conclusion. Furthermore, a conventional statistical test, usually assuming a certain distribution for its samples, may lead to exaggerated explanation, which is detrimental to the quality of a decision. So, in order to avoid the waste of our social cost from misunderstanding of the elderly, and to make the most use of our limited social resource, when we investigated the elderly people’s personal characteristics and expectations, we tried to apply the soft calculation of the fuzzy theory, proposed the counter-fuzzy transformation, and, by using the median test and variance test, established a nonparametric fuzzy statistical model for small-sized samples and for parameters of the fuzzy number or fuzzy interval types. The analyses of real-world examples demonstrated that this method of statistical test can analyze the problems of fuzzy samples, and can hopefully contribute to improved analysis and decision making of the elderly people’s issues, and apply this method on the investigation of other fuzzy social issues. Key words: counter-fuzzy transformation, fuzzy statistical analysis, median test, variance test, aging society.
